Bounds for Codes and Sphere Packings,ing problems in 2-point-homogeneous spaces. A simplified account is given of the general machinery developed by Kabatiansky and Levenshtein for setting up such problems as linear programs. Many other recent bounds are also described.

The Golay Codes and The Mathieu Groups,Miracle Octad Generator) and the hexacode are computational tools that make it easy to perform calculations with these objects. The . and the tetracode perform similar services for the ternary Golay code of length 12, the Steiner system . (5, 6, 12), and the Mathieu group ...
